The first generation Crystalens accommodating intraocular lens (IOL) (eyeonics) was approved by the FDA in November 2003 and has since undergone two revisions. The first involved modification of the lens optic to a "square" rather than smooth edge in order to reduce the incidence of asymmetric capsular fibrosis, which could cause capsular contraction and IOL tilt

Applying a specific number of FS-induced cuts to the crystalline lens could restore accommodation.

PresbyLASIK treatment uses the principles of LASIK surgery to create a multifocal corneal surface aimed at reducing near vision spectacle dependence in presbyopic patients. This treatment constitutes the next step in the correction of presbyopia after monovision LASIK.1-3 Among the presbyLASIK techniques, central presbyLASIK 4 creates a central area, which is hyperpositive for near vision leaving the midperipheral cornea for far vision. 5 Positive clinical results of this surgical technique have been recently reported 4 and also tested objectively with a light propagation algorithm. 6

An overall spectacle independence of 90% was achieved, however, I have found that some patients do still require glasses when using a computer for intermediate vision

It has been discovered that the equatorial diameter of a lens directly influences accommodation and thus presents a sound target for presbyopia treatment interventions

In our experience so far, PML is a very successful procedure that has been well-accepted by patients and is in high demand at our centre. Currently, about 50% of our patients are PML candidates

Ophthalmic surgeons have been implanting multifocal lenses for several years, not only in cataract surgery, but also to offset the accommodation lost as a consequence of age. With the newest generation of lenses, more than 80% of refractive and cataract patients can now enjoy life without glasses.

Presbyopia Correcting IOLs (PCIOLs) are perhaps the most significant technological advancement in recent ophthalmic history. These lenses not only provide patients with the option of seeing near, intermediate, and distant objects without dependence on glasses for most of their daily activities — they could also become the single most important cornerstone for building a successful ophthalmic practice, both now and in the foreseeable future.
